FMPROVE lVlENTlN FAN- ATTACHMENTS FOR SEWING-'MACH INES.

215,388. dated May 13, 1879 application filed To all whom it may concern.- 1 *Be itknowm that I, ARTHUR A. NAUCK, of Washington, in the county of Washington and District of Columbia, have invented certain new and useful Improvements in Adjustable Fanners for Sewin'g' Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

Figure 1 is a side elevation of my improved fan, and shows the method of attaching the same to a sewing-machine. Fig. 2 is a vertical longitudinal sect-ion through the hollow standard support ng the fan, and shows the mode of operating the same. Fig. 3 is a rear elevation of the clamp for holding the connecting-rods at any desired length; Fig. 4, a side elevation of the same. Fig. 5 is a topplan view of the clamp for holding the fan; Fig. 6, a side elevation of my improved fan, showing how the same may be attached to a rocking-chair.

This invention consists, first, in certain devices for operating a fan or fans by means of the attachment of said fan or fans to the pitman or treadle of a sewingmachine, or to any machine driven in an analogous manner, by reason of which devices a greater amount of agitation is produced in the air with less expenditure of power than in any other form of fan heretofore constructed; second, the construction of a fan that shall be capable of bein g operated by other means than the abovenamedas, for instance, the attachment of the driving-rod of said fan to the rocker of a chair.

Referring to the drawings, A represents a portion of the table of a sewing-machine; K, the legs of same 5 L, the drivingwheel; N, the pitman; M, treadle. B is a hollow standard, which supports the fan. The standard B moves or is adjustable up and down inasleeve, I, which sleeve is secured to the top of the table by screws or otherwise. The standard may be placed at any height, and may also be I turned upon its vertical axis, and secured at i same by means of the set-screw in I.

1 Within the standard B,'and just fitting the bore thereof, is a block orplunger, 0, Figs. 1, 2, and 6. The plunger 0 is moved up and down in the standard by means of connectingrods G G, the upper rod, G, being connected with the plunger by a screw-connection, while the lower end of said rod passes through a clamp, H, in which clamp it is held at any height by means of a set-screw, h. To this clamp the upper end of rod G is rigidly secured in any known manner, while the lower end of the latter rod is pivoted to the pitman near its junction with the treadle, or at any other point on the pitman; or the rod may be connected directly to the treadle, if desired by the operator. By means of the construc tion of the clamp H, which construction is shown in Figs. 3 and 4, I am enabled to readily adjust the rods to any given length, while the set-screw h serves to securely hold and fasten them together when so adjusted.

E is an oscillating arm, secured or pivoted at its central point in lugs or ears upon the upper part of the standard B. One end of this arm. is connected to the plunger 0 by the rod D and thumb-screw 0. This thumb-screw is constructed to readily slide up and down in the slot or opening in the side of the standard B, and also allows the arm and rod to be readily-taken apart for packing and other purposes. The arm E and rod D are connected in any convenient manner, care being taken to allow the rod to freely work when so connected.

To the opposite end of the arm E is attached a clamp, F, Figs. 1, 5, and 6, for securing the fan. This is effected by means of a screwbolt, which passes through the clamp from hotthumb-nut, for the purpose of tightening the clamp upon the fan when the latter is in posi* tion (closed oropen) within the clamp, as shown in Fig. 1, in which figure g represents the stock orhandle of an ordinary hand-fan as now in use.

The operation of the fan is as follows The standard B and rods G G being adjusted to the proper height by means of their respective setscrews, and the treadle being worked,

tom to top, and having upon its upper end a i the rods G G and the plunger 0, to which they are connected, are caused to move up and down, which movement, through the connecting-rod 1), causes the arm F to rock, by which the fan is moved vertically, as described.

Fig. 6 is a modification of my improvement, showing the manner of attaching the same to an ordinary rocking-chair. In this figure, O is the rocker of the chair; P, the standard to support the fan mechanism. The upper end of said standard is bent at right angles, and terminates in a bearing, K, through suitable manner to the rocker O. The fan is worked by the up-and-down' motion of therocker, consequent upon rocking the same.

What I claim, and desire to secure by Letters Patent, is-

1. In an adjustable fanning device, the hollow standard B, having a slot or opening in its side, the sleeve I, having set-screw i, the plunger 0, rod G, connecting-rod D, and fan-arm E, having clamp F, all arranged to operate with respect to each other substantially as and for the purpose set forth.

2. In an adjustable fanning device,the standard B, plunger 0, connecting-rod D, and fanarm E, in combination with rods G G, said rods being adjustably connected together by means of clamp H, secured to rodG, and having separate opening for rod G and thumbscrew 71, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I aflix my signature in presence of two witnesses.

ARTHUR A. NAUOK.
